invalid_count = 0;
max_invalid = 3;

    user_input = input('Enter a valid input: ', 's');
    
    if is_valid(user_input)
        % Do something with the user input
        break;
    else
        invalid_count = invalid_count + 1;
        if invalid_count >= max_invalid
            error('Too many invalid entries. Please rerun the program.');
        end
        fprintf('Invalid entry. Please try again.\n');
